Server issues

[sgrabowski]

Hi all. I'm at my limit for my linux capabilities and need some pointers as how to fix these problems with my 12.04 Server:

1. I have set up unattended updates and now they are failing because there's a problem with unmet dependencies:

stefan@orieta:~$ sudo apt-get upgrade
Reading package lists...
Building dependency tree...
Reading state information...
You might want to run ‘apt-get -f install’ to correct these.
The following packages have unmet dependencies.
 samba : Depends: samba-common (= 2:3.6.3-2ubuntu2) but 2:3.6.3-2ubuntu2.1 is installed
         Depends: libwbclient0 (= 2:3.6.3-2ubuntu2) but 2:3.6.3-2ubuntu2.1 is installed
E: Unmet dependencies. Try using -f.

So I tried that, but it seems to be having issues with Twonky Server. I have completely removed the twonky install, so I don't understand why I am getting this issue:

stefan@orieta:~$ sudo apt-get -f install

2. I have a drive in the server what will not go into standby. I have set up HDPARM to send the three data drives to standby after 10 minutes of inactivity, but /dev/sdb1 refuses to go into standby, even after using the '-y' flag.

Any advice or pointers on these two issues would stop me pulling my hair out, and end up with the server I've always wanted!!

Have did you install and remove twonky? it looks like apt still thinks it is installed.

Try this:

sudo apt-get purge samba && sudo apt-get install samba

Thanks for the pointer, but I'm still getting errors:

What happens when you try to purge twonky?

The system still thinks it is installed and that is probably why it is failing.

Hmm, the first thing to do when you installed a server, is to turn auto-screwups/updates off.

You have to evaluate each update on another machine (physical or virtual) first, before you apply it to a critical machine.

[sgrabowski]

CharlesA: Twonky was installed via a shell script so purging twonky bring up unable to locate package error. I have removed all the files referenced in it's install log, including the init.d reference.

HermanAB: This is my only ubuntu machine, and its only a home media server, so cannot not really be classed as critical. I just want to get it working properly.

Hi!
I had this issue as well and came to this thread. I fixed my issue by simply doing
sudo apt-get autoremove libwbclient0

I could install the stuff I needed after this.. but I didn't have the other dependency.. just wanted to pass this along for reference is all...

I had the same problem (preceded by 12.04 MySQL dependency woes). I had removed all Twonky files referenced in the twonky.sh installer, and having resolved the dependency issues still found that the Twonky messages referenced above were being shown when doing an unrelated update (in this case updating Cups).

By grepping

grep -R 'Twonky' /etc/init.d/*

I found loads of references to Twonky, all symlinks through to /lib/init/upstart-job which had been entirely replaced with the twonky.sh installer.

I then move upstart-job out of the folder and ran

apt-get install upstart --reinstall

which reinstates /lib/init/upstart-job and allowed me to upgrade using apt-get without any errors.

Be warned that you must verify that upstart-job is indeed 'corrupt' before doing this - as I understand it upstart is a pretty critical process and not to be messed with unless you are sure that it has definitely broken. At this point I haven't verified that there are no ongoing issues, though getting apt-get back in operation at a minimum is somewhat helpful and I have been available to reboot without major issues.
